NOW Ultra Omega-3
Brand: NOW · Form: SOFTGEL CAPSULE [E0161]
Our assessment
The evidence shows that NOW Ultra Omega-3 is a fish oil supplement. However, our assessment focuses on calcium, a key mineral often taken alongside omega-3s. Data indicates calcium supports bone density and neuromuscular relaxation [NIH ODS]. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It works through bone mineralization to support bone density and mineral deposition. It also aids neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS]. For optimal absorption, you should take calcium with food.
Safety profile
The FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should take NOW Ultra Omega-3 as directed on the label. If you are also considering calcium, start with a moderate dose and get your blood levels checked. Avoid exceeding the tolerable upper intake level, and take calcium separately from medications listed in the safety profile [NIH ODS]. Data on specific benefits for NOW Ultra Omega-3 beyond general omega-3 effects is not available.
